2. Parasitic capacitance due to the chip bond pad, ESD protection devices, and signal routing: 2.04 pF
3. 8 pF noise damping capacitor
4. Sampling capacitor at the sample and hold circuit. Capacitor C1 is normally disconnected from the input and is only
connected to it at sampling time: Cgain = 1.4 pF for x1 gain, 2.8 pF for x2 gain, and 5.6 pF for x4 gain.
5. S1 and S2 switch phases are non-overlapping and operate at the ADC clock frequency.
